Zero-Dependent Bivariate Poisson Distribution with Applications

open access: yesMathematics, 2023
The bivariate Poisson model is the most widely used model for bivariate counts, and in recent years, several bivariate Poisson regression models have been developed in order to analyse two response variables that are possibly correlated. In this paper, a

A POISSON-POISSON MODEL TO ANALYZE CONGESTION DATA [PDF]

open access: yesAdvances and Applications in Statistics, 2018
Summary: Congestion in internet network often worsens the performance of the network. An analysis of congestion data plays a significant role in congestion detection and control. To detect and control congestion, analysis of number of packet arrival, packet inter arrival times, throughput, queuing delay, etc. are some important phenomena.

A New Poisson Generalized Lindley Regression Model

open access: yesAustrian Journal of Statistics, 2023
In this paper, a new count distribution is introduced. It is a mixture of the Poisson and generalized Lindley distributions. Statistical properties of the proposed distribution including the factorial moments, probability generating function, moment ...

Poisson-Driven Stationary Markov Models [PDF]

open access: yesJournal of Business & Economic Statistics, 2017
We propose a simple yet powerful method to construct strictly stationary Markovian models with given but arbitrary invariant distributions. The idea is based on a Poisson-type transform modulating the dependence structure in the model. An appealing feature of our approach is the possibility to control the underlying transition probabilities and ...

Integrability vs Supersymmetry: Poisson Structures of The Pohlmeyer Reduction [PDF]

open access: yes, 2011
We construct recursively an infinite number of Poisson structures for the supersymmetric integrable hierarchy governing the Pohlmeyer reduction of superstring sigma models on the target spaces AdS_{n}\times S^n, n=2,3,5.

NEGATIVE BINOMIAL REGRESSION AND GENERALIZED POISSON REGRESSION MODELS ON THE NUMBER OF TRAFFIC ACCIDENTS IN CENTRAL JAVA

open access: yesBarekeng, 2022
Traffic accidents that always increase along with the increasing population growth and the number of vehicles impact the national economy. The number of traffic accidents is a count data that a Poisson distribution can approximate. The Poisson regression

Poisson sigma models and symplectic groupoids [PDF]

open access: yes, 2000
We consider the Poisson sigma model associated to a Poisson manifold. The perturbative quantization of this model yields the Kontsevich star product formula. We study here the classical model in the Hamiltonian formalism.

An alternative hyper-Poisson integer-valued GARCH model with application to polio, internet protocol and COVID-19 data

open access: yesAIMS Mathematics, 2023
Time series of counts are observed widely in actuarial science, finance, epidemiology and biology. These time series may exhibit over-, equi- and under-dispersion.

Numerical approximation of the Euler-Poisson-Boltzmann model in the quasineutral limit [PDF]

open access: yes, 2010
This paper analyzes various schemes for the Euler-Poisson-Boltzmann (EPB) model of plasma physics. This model consists of the pressureless gas dynamics equations coupled with the Poisson equation and where the Boltzmann relation relates the potential to ...
